Evaluation and Design Methodologies - Embodied Conversational Agents: Effects on Memory Performance and Anthropomorphisation

Abstract

It is often assumed that the use of Embodied Conversational Agents (ECAs) in human-computer interfaces improves human-computer interaction. Because of their appearance and because they show human-like communicative behaviour, users tend to ascribe human characteristics to ECAs or anthropomorphize them. Since interacting with another human being comes natural to people, anthropomorphisation of agents in an interface is thought to improve the process of communication. As a result, other usability aspects, such as satisfaction and learnability, would probably benefit. This paper describes a study into anthropomorphisation of ECAs and their effect on memory performance. The results of our study show that the presence of an ECA has a positive effect on retainability of information, but that this effect is not necessarily influenced by anthropomorphism.
